Editing Rioja DOCa (section)

=== New authorized varieties ===
In 2007, the Regulating Council of the D.O.Ca. Rioja authorized, for the first time since 1925, the incorporation of some additional varieties within the limits of the denomination, changes that were reflected in two modifications of the existing Regulation approved in 2004: BOE-A-2008-4991 and BOE -A-2009-8950, but this has been subject to subsequent amendment.<ref>Current regulations (in Spanish) can be viewed at https://uk.riojawine.com/en/36-legislation.html</ref>

The currently permitted additional varieties are the following:

* Indigenous red varieties: [[Trousseau_(grape)#Spain|Maturana tinta, (also called Maturana parda or Maturano)]]
* White varieties:
** [[Indigenous (ecology)|Autochthonous]] varieties: Maturana blanca, [[Tempranillo blanco]] and Turruntés or Torrontés (not the same as the varieties named Torrontés cultivated in other parts of Spain and the rest of the world).
** Foreign varieties: [[Chardonnay]], [[Sauvignon blanc]] and [[Verdejo]].

These new authorized varieties can only be planted in substitution, so as not to increase the vegetable mass of the Denomination.

In the case of the new autochthonous varieties, both red and white, no limit is set on the percentage that the wines must carry, which is why the production of single varietal wines of these grapes is allowed. On the contrary, in the foreign white varieties ([[Chardonnay]], [[Sauvignon blanc]] and [[Verdejo]]) it is established that they can not be the predominant ones in the final composition of the wine. Therefore, if the varieties are indicated on the label, the autochthonous white variety (Viura, Garnacha blanca, Malvasía de Rioja, Maturana blanca, Tempranillo blanco or Turruntés) must always be listed first.

The incorporation of these new varieties was made with the aim of recovering Rioja's viticultural heritage, in the case of autochthonous grapes, and to increase the competitiveness of Rioja whites in the international market, in the case of foreign white varieties.
